The Short Call Diagonal Option Screener uses a strategy that involves selling a nearer term expiration ITM call and buying a longer term OTM expiration higher strike call against it.
The bear call diagonal strategy is one where you think the price of the underlying stock will remain stable or slightly decrease.
Using a bear call strategy, you sell call options, and buy the same number of call options at a higher strike price as protection. The calls are for the same underlying stock, expiring at different dates.
- You sell 1 call with a nearer term expiration.
- You buy 1 higher strike call.
When you first access the page, we show screener results from a default set of filters that are in the "Set Filters" tab. You may use these default filters to fine-tune the screener, or you can open one of the screeners you've previously saved in your account using the "LOAD A SCREENER" drop-down.
The results from the screener are initially sorted by descending "Net $ Delta."
The screener displays probability calculations based on the delayed stock price at the time the strategy is updated. Strikes that have not traded today are excluded from the results.
Options start updating for the new trading day at approximately 9:50a.m. ET. Options information is delayed approximately 25 to 30 minutes, and is updated approximately every 5-minutes through-out the trading day.
Note: Expired options are removed from the website Monday - Friday at 7:45pm ET.
Main features of the Screener include:
- Customizable filters, based on over 150 different data points, with hundreds of different combinations. In addition, you may screen on many of Barchart's most popular pages such as Top 100 Stocks, New Highs and Lows, New Recommendations, specific pages in the Investing section, and more. You may also screen based on one or more of your Watchlists or Portfolios. This short tutorial gets you started with using filters on screeners.
- Save a Screener: When you've defined filters that you want to use again, save the screener.
- Load a Saved Screener: Select a previously saved set of Screener filters to view today's results.
- Share Your Screener: Once you've saved a screener in your Barchart account, you can create a "share link" to send to your friends, associates, or any other interested parties. See details below.
- Barchart Screeners: On many of our screeners, you can select a sample screener provided by Barchart. You can modify the filters and save your new screener to your account.
- Save to Watchlist: You may save up to 1000 symbols from your Screener results to a new Watchlist, or append the results to an existing Watchlist.
- Custom Views: Once on the results page, you may change your view to the "Filter" view (showing you the fields you've screened for), or any of your saved Custom Views.
- View the Results using Flipcharts: Page through charts of the symbols on the results page.
- Download: Download up to 1000 screener results to a .csv file. The Download will include the data fields for the View you use.
- Automatic Screener Emails: This option is available for Barchart Premier Members only. When you save a screener, you can opt to receive the top results via email along with an optional .csv file of the top 1000 results. Emails can be sent at different times, based on the screener.
Note: When selecting the Filter View for your Screener email, a filter must identify a specific search value in order for it to be included in the email.
Filters
Barchart Premier subscribers can add or modify different filters on the screener to find calls on the most favorable stock options.
Reordering Filters
Once filters are added, you may drag and drop them in the SET FILTERS tab to reorder the way they appear on the RESULTS tab (when using the Filters View). Each filter you add has the "Order" icon which is used to reposition it.
Deleting Filters
To remove a filter from your screener, click the checkbox to the left of the filter name, then click the red "Delete Filters" button at the top of the column. You may also select all filters for deletion by clicking the checkbox at the top of the column, which selects ALL filters for deletion. You will be asked to confirm your decision to delete.
So you can focus on the best options, the screener starts by applying these default filters. Filter settings should be adjusted to match your trading requirements.
- Security Type: Stocks
- Days to Expiration Leg1 and Leg2 (monthly and weekly expirations) is 1-60 days.
- Options Volume Leg 1 and 2: for US market, must be greater than or equal to 100. For Canadian market, must be greater than or equal to 1.
- Open Interest Leg 1 and 2: for US market, must be greater than or equal to 500. For Canadian market, must be greater than or equal to 5.
- Bid Price Leg 1 must be greater than 0.05
- Ask Price Leg 2 must be greater than 0.05
- Moneyness Leg 1 is between -10% to 0%
- Moneyness Leg 2 is between -25% and -6%. Moneyness refers to the relative position of the underlying asset's last price to the strike price. When a call option's Moneyness is negative, the underlying last price is less than the strike price; when positive, the underlying last price is greater than the strike price. When a put option's Moneyness is negative, the underlying last price is greater than the strike price; when positive, the underlying last price is less than the strike price.
In addition:
- The stock price must be greater or equal to 1.00.
- Max Loss must be greater than $0.00.
- The option must not be a "restricted" option (the option cannot be based on a split stock).
- Strikes that have not traded today are excluded from the results.
Note: Non-standard or "restricted" options (options quotes marked with an asterisk * after the strike price, and found on an individual symbol's options page) are automatically removed from the screener. A "restricted option" is typically created after spin-offs or mergers, and is not tradeable.
Probability Calculation
We take the underlying stock price (l), the target price (b), days to expiration (t) and the implied volatility (v) to calculate probability:
Probability Above = 1-NORMSDIST (LN(b / l) / (v*SQRT (t / 365)))
Probability Below = NORMSDIST (LN (b / l) / (v*SQRT(t / 365)))
b = target price
l = underlying last price
v = implied volatility
t = days to expiration
Bear Call Spread Break Even: Probability of the underlying trading BELOW the break even point at expiration and profiting from the trade.
Bear Call Spread Max Risk Probability: Probability of the underlying expiring at or above the long call strike price at expiration.
Maximum Annual Percent Return: Available as a separate filter to add to the screener, the calculation is as follows:
Max Ann %Rtn = ( ( ( MaxProfit / (StrikeDiff - MaxProfit) ) / DTE ) * 365 ) * 100.0
where
Max Profit = [Leg1 Bid - Leg2 Ask]
Strike Diff = [Leg2 Strike - Leg1 Strike]
DTE = Days till Option Expiration.
Note: The calculation is annualized by dividing the result by 365 (days).
Views
The Results page contains three standard views. You may switch the view using the links at the top of the screener results table. The Main View shows the Volume and Open Interest for each option, while the Dividend & Earnings View can be used to highlight strategies with upcoming dividends and earnings. The Filter view shows you the data contained in the field(s) you've added to the screener.
Main View
- Symbol - the underlying equity. Clicking on the symbol will take you to the current quote page.
- Price~ - the delayed stock price at the time the strategy is updated for the underlying equity.
- Expiration Leg1 - the expiration date of the Leg 1 option
- Leg1 (Sell) Strike - the price at which the underlying security can be bought if the option is exercised.
- Leg1 Bid - the premium to sell this option.
- Expiration Leg2 - the expiration date of the Leg 2 option.
- Leg2 (Buy) Strike - the price at which the underlying security can be bought if the option is exercised.
- Leg2 Ask - the premium to purchase this option
- Net Credit or Max Profit - the potential return of this strategy. Max Profit is: Leg1 Bid (ITM Call) - Leg2 Ask (OTM Call)
- Max Loss - Max Loss = Strike Difference - Net Credit (if closed at the first expiration date)
- Risk/Reward% - Risk/Reward Ratio = (Strike Difference - Net Credit) / Net Credit (if closed at the first expiration date)
- Leg1 Delta - Delta measures the amount an option price will change as a result of a $1.00 price change of the underlying security.
- Leg2 Delta - Delta measures the amount an option price will change as a result of a $1.00 price change of the underlying security.
- Net $ Delta -
- a. Leg2 Ask + ((Leg2 Strike - Security Price) * Leg2 Delta)
- b. Leg1 Bid + ((Leg2 Strike - Security Price) * Leg1 Delta)
- Net $Delta = Step b. - Step a. - Net Credit (Leg1 Bid - Leg2 Ask)
- Net $Theta - the time decay. Net $Theta =
- Step 1: Calculate theta loss per leg:
a. Leg2 theta loss = {Leg2 theta * Leg1 DTE}
b. Leg1 theta loss = {Leg1 theta * Leg1 DTE}
- Step 2: Calculate decay legs by theta loss
a. Leg2 decay = Leg2 Ask - Leg2 theta loss
b. Leg1 decay = Leg1 Bid - Leg1 theta loss
- Step 3: Calculate the spread using the new bid and ask values
a. Theta spread = Leg1 decay - Leg2 decay
(spread can not be wider than Leg1 decay)
Net $Theta = Theta spread - Net Credit (Leg1 Bid - Leg2 Ask)
Dividend & Earnings View
- Dividend - the dividend the equity pays on the Ex-Dividend Date. On the morning of the Dividend Ex-Date, the stock's price is lowered by the amount of the dividend that was just paid.
- Dividend Ex-Date - the first day on which the stock trades without the dividend. If you wish to receive the dividend, you must own the stock by the close of market on the day before the Dividend Ex-Date. Many times, a covered call is exercised early so the buyer can own the stock and collect the dividend. This typically happens to ITM options the day before the Dividend Ex-Date.
- Earnings Date - The date on which a company is expected to release their next earnings report. The prices are more volatile, which tends to inflate the prices of the near-the-money strikes. During a contract period when there is an earnings report due, the earnings announcement can dramatically shift the range in which the stock has been trading.
Delete Screener
Once you save a screener in your Barchart account, you may delete it from the Results tab. Just click the "Delete Screener" button. You may also manage and delete your screeners by clicking the "Organize My Screeners" button.
Share Screener
Once you save a screener to your account, you may share either the details of the screener (including all your filters) or just the results of your screener with anyone you send the link to.
First, save your screener, making sure the view and sort you select in the saved screener modal is the one you want to share. You may share any of our "Standard" views (Main, Technical, Performance, etc.) or the Filter view. Shared screeners saved using one of your Custom views will only share the Filter view, as the Custom view is specific to your Barchart account.
Next, click the "share" link found on the Results tab. You will be asked what to share:
- Share Screener with Filters - the people you share the link with will be able to save the same screener in their Barchart account and view/modify the filters you used.
- Only Share the Results - the people you share the link with will not be able to save this screener in their Barchart account or view the filters you used to create the screener. This option would be used if you wish to keep your screener filters proprietary.
The share link is copied to your clipboard, and you are now free to send that link to anyone. Any further changes you save to your screener are automatically updated on the "share link" you initially generated.
Furthermore, if the end-user bookmarks the shared link (regardless of whether filters were shared or not) they will always see new results each time they open the link.
